Abstract: The loading and start-up phase of the THTR 300 is controlled by an external neutron source. To treat positions for this source outside of the reactor axis 3-dimensional neutron physical computer modeln are necessary. The presented study treats the problem of the excentrically arranged neutron source in 3-D-geometry. Beyond that comparisons to 2-D-approximations are performed and the model-specific differences are discussed with regard to the Interpretation of detector signals. lt is shown that the 2--D-modeln concerning integral resuits like multiplication constant and total reaction raten deviate only little from the 3-D-representation. 0n the other hand distinct differences exist for the neutron distribution, which influence evidently the right positioning of detectors. An arrangement of the detector in a distance of 1 .5 m under the source plane of the reactor fulfills the discussed criteria.
